    LAYOUT

    RACING LAYOUT

     When aiming for true performance efficiency, we had chosen to design the exhaust with the least amount of bends as possible. Just like the true purpose built race cars, in a racing layout design, yet to still comply with the stock body design so it can be fitted to any street used vehicles.

    A : MAIN SILENCER/ TAIL END

    Compared with the stock design, our design is single piping all the way for max weight reduction. We have also focused on the design of the muffler to produce the best exhaust sound without compromising performance.

    B : MAIN PIPE

    The pipe diameter was chosen for optimum exhaust flow efficiency. For performance use in mind and weigh reduction. Thus the slide joints was made instead of using the conventional flange and gasket design.

    C : SUB SILENCER

    This sub silencer was designed with a simple structure and minimal size to reduce unwanted noise. Without hindering exhaust gas flow.

    SECTION PIPE ASSEMBLY

    The conventional style flange is not used to help reduce weight even further. The use of the springs and clamps eliminates the need for gaskets as well.
